Or you can sell the house to a hotel developer, or for a conference centre, or to someone who will turn the manicured gardens into an organic farm. In any case, if the house and land are wealth they can be turned into economic power. If they can't, they're not wealth to begin with.
Or if the house really has sentimental value for you and you want to die in it you can take a reverse mortgage on the damn thing. "It's the statue, man, The Statue."
And use an LLC or LLP wrapper to do so.
Then when the time comes to go into sheltered accommodation, you still have a (100-x)% share of the ownership and of the market rental, and have the option of selling the property conventionally, or bringing in another "Occupier" into the property and selling some or part of your share of the rentals he pays over time.
Or to minimise your Inheritance Tax liability when you die in the house you love, you can pass over some of your Equity Shares over time to your kids and pay them a rental in cash or even in more equity shares instead of cash.
Infinitely configurable, (and you don't need a Will cos the LLP agreement says what happens when you die). You won't read much about it because simple models like this don't appeal to professional advisers paid by the hour, rather than by the outcome. "Any economic unit can emit money. The serious problem is to get it accepted" Hyman Minsky
Sorry, I can't think on a full stomach. Why does the investor give you the money, what is the "agreed market rental" and who lives in the house? "It's the statue, man, The Statue."
